Congenital undescended scapula is congenital structural abnormality which affects only one side usually. Scapula located higher than the usual and rotating deformity that inferior angle to medial side, superior angle to lateral side is common. This report presents one case of the surgical therapy of a sprengel deformity patient who passed an optimal operation period with age $3{\sim}7$years old, and includes brief review of the literature. 7 years old boy whose chief complaint was the limitation of left scapular-thoracic movement and he had an omovertebral bone bridge and periscapular muscle atrophy. There was improvement of motion ranges and cosmetic problems after surgical treatment.

This study was performed to evaluate the influences of the passive glenohumeral rotation on the scapulothoracic motion. We took anteroposterior radiograms of the right shoulders including the thoracic vertebrae with supine position in 10 normal male adults, at 0 degree abduction, 45 degrees abduction and 90 degrees abduction in scapular plane and in neutral rotation, maximal internal rotation and maximal external rotation in each abduction view. The scapulothoracic motion was measured as the distances between the vertical line drawn from the spinous process of the 7th cervical vertebra and the inferior and superior angles of the right scapula respectively. At 0 degree abduction, the distances were not changed in internal rotation relative to neutral rotation, but decreased significantly in external rotation, that is, the scapula shifts medially on external rotation. At 45 degrees abduction, the distances were increased significantly only in internal rotation, that is, the scapula shifts laterally on internal rotation. At 90 degrees abduction, the scapula rotated laterally on internal rotation and medially on external rotation. In conclusion, when a physician examines the rotation of the shoulder joint, he cannot exclude the scapulothoracic motion just by examining the patient with supine position. And we concluded that the rotatory movement of the shoulder is not solely contributed to the glenohumeral motion.

Purpose: The purpose of this study was to investigate the effects of using proprioceptive neuromuscular facilitation (PNF) exercise in the progressive sitting position on the dynamic balance ability of a patient with a cerebellar injury. Methods: The subject had ataxia due to cerebellar injury. The subject participated in a PNF bilateral scapular pattern exercise with stabilizing reversal technique during a progressive sitting position session as well as baseline for 20 minutes a day for 4 weeks. In the first session, PNF exercises were performed at a height of 40 cm for 10 minutes, and in the second session they were performed at 50 cm for 10 minutes from a lower center of gravity (COG) to a higher COG sitting position. We used the Berg Balance Scale (BBS), Five-Times-Sit-to-Stand Test (FTSST), and the Timed Up and Go Test (TUGT) to measure the subject's dynamic balance ability every two days through the entire session. Results: After participating in the program, the subject's dynamic balance ability improved compared to the first baseline, as measured by BBS (2 points increased), FTSST (5.3 sec decreased), and TUGT (2 sec decreased). The increase was also maintained in the second baseline session. Conclusion: PNF exercise using bilateral scapula patterns with a stabilizing reversal technique helps to enhance the dynamic balance ability of a cerebellar injury patient.

Purpose: Continuous use of a smartphone increases the angle of forward bending of the user's cervical vertebrae, causing pain in the shoulders and back, including the thorax, lumbar region, and vertebrae. Although there are many studies on changes in the cervical spine due to smartphone usage, the changes in the shoulders, thoracolumbar spine, and pelvic have rarely been compared. The purpose of this study is to investigate the change in the spinal segments, shoulders, and pelvic when using a smartphone with both hands while in the standing position. Methods: This study was conducted on 35 adults in their twenties. The selection criteria for the subjects were limited to those in a similar age group, thus excluding posture differences according to age, and to those who did not have specific diseases or pain in the spinal and musculoskeletal system for 12 months prior to the study. In this study, we used a 3D spinal diagnostic imaging system (Back Mapper, Frickenhausen) to compare the changing conditions in each vertebral segment before and during smartphone usage with both hands while in the standing position. Posture differences according to smartphone usage were compared using the paired t-test for the motion of each spinal segment. Results: This study showed that the thoracic and lumbar angle increased posteriorly during smartphone usage (p<0.05). In addition, the anterior rotation angle of the shoulder bone significantly increased, but no significant difference occurred in the pelvic region. Conclusion: Based on the results of this study, smartphone usage with both hands while in the standing position showed that the spine, as a whole, forms a kyphotic curve. Therefore, we propose to present a postural guideline for correct smartphone usage, considering the change in each vertebral segment.

Purpose: The purpose of this study was to investigate the effect of visual and auditory feedback combined with theraband exercise in rounded shoulder posture. Methods: There were 43 adults with rounded shoulder posture who had a distance of 2.5 cm or more from the posterolateral of the acromion to the table in the supine position that participated. The participants were randomly divided into four groups: those with visual feedback from the lateral view (visual feedback; VFB, n = 11) provided, those with auditory feedback of praise (auditory feedback; AFB, n = 10) provided, those with visual feedback and auditory feedback (visual auditory feedback; VAFB, n = 11) provided, and those without any feedback (control group; CON, n = 11). Theraband exercise with or without feedback was carried out three times per week for three weeks. To confirm the effect of theraband exercise with visual feedback and auditory feedback on pain, range of motion (ROM), posture, and psychological variables were measured before and after exercise in participants with rounded shoulder posture. Results: The VAFB group showed significant differences in pain, ROM, posture, and psychological variables when compared before and after treatment. However, the differences among the VAFB, VFB, AFB, and CON groups were significant in the ROM of abduction, the New York Posture Rating, and the scapular index. Conclusion: In conclusion, theraband exercise combined with visual feedback from the lateral view and auditory feedback by praise improved rounded shoulder posture. Moreover, auditory feedback was more significant statistically than visual feedback.

Background: In the present study, the age- and sex-adjusted Constant score (CS) in a normal Indian population was calculated and any differences with other population cohorts assessed. Methods: The study participants were patients who visited the outpatient department for problems other than shoulder and healthy volunteers from the local population. Patients without shoulder pain/discomfort during activity were included in the study. Subjects with any problem that might affect shoulder function (e.g., cervical, thoracic spine, rib cage deformity, inflammatory arthritis) were excluded. Constant scoring of all participants was performed by trained senior residents under the supervision of the senior faculty. Shoulder range of movement and strength were measured following recommendations given by the research and Development Committee of the European Society for Shoulder and Elbow Surgery (2008). A fixed spring balance was used for strength measurement; one end was fixed on the floor and the other end tied with a strap to the wrist of the participant, arm in 90° abduction in scapular plane with palm facing down. Results: Among the 248 subjects (496 shoulders), the average age was 37 years (range, 18-78 years), 65.7% were males (326 shoulders) and 34.3% females (170 shoulders). The mean CS was 84.6±2.9 (males, 86.1±3.0; females, 81.8±2.9). CS decreased significantly after 50 years of age in males and 40 years of age in females (p<0.05). The mean CS was lower than in previous studies for both males and females. Heavy occupation workers had higher mean CS (p<0.05). A linear standardized equation was estimated for calculating the adjusted CS for any age. Conclusions: Mean CS and its change with age differed from previous studies among various population cohorts.

Purpose : This study was to understand about the measurement of shoulder motion fraction and motion ratio. We proposed the radiological criterior of glenohumeral and scapulothoracic movement ratio. Materials and Methods : We measured the motion fraction of the glenohumeral and scapulothoracic movement using CR(computed radiological system) of arm elevation at neutral, 90 degree, full elevation. Central ray was $15^{\circ},\;19^{\circ},\;22^{\circ}$ to the cephald for the parallel scapular spine, and the tilting of torso was external oblique $40^{\circ},\;36^{\circ},\;22^{\circ}$ for perpendicular to glenohumeral surface. Healthful donor of 100 was divided 5 groups by age(20, 30, 40, 50, 60). The angle of glenohumeral motion and scapulothoracic motion could be taken from gross arm angle and radiological arm angle. We acquired 3 images at neutral, $90^{\circ}$ and full elevation position and measured radiographic angle of glenoheumeral, scapulothoracic movement respectively. Results : While the arm elevation was $90^{\circ}$, the shoulder motion fraction was 1.22(M), 1.70(W) in right arm and 1.31, 1.54 in left. In full elevation, Right arm fraction was 1.63, 1.84, and left was 1.57, 1.32. In right dominant arm(78%), $90^{\circ} and Full motion fraction was 1.58, 1.43, in left(22%) 1.82, 1.94. In generation 20, $90^{\circ} and Full motion fraction was 1.56, 1.52, 30' was 1.82, 1.43, 40' was 1.23, 1.16, 50' was 1.80, 1.28, 60' was 1.24, 1.75. There was not significantly by gender, dominant arm and age. Conclusion : The criterior of motion fraction was useful reference for clinical dignosis the shoulder instability.

The purpose of this study is to analyze the effects of exercise program for prevention of falling on physical fitness, posture and fall prevention self-efficacy for elderly women. 30 females above the age of 65 were subjects for this study. Over an twelve week period, 14women in the experimental group performed exercise 2 times a week for 60 minutes per session. 16women in the control group didn't participate in the exercise program. The independent variable was a exercise program for prevention of falling. Dependent variables were physical fitness, posture and fall prevention self-efficacy. Prevention of falling exercise program is consisted of an elastic band using exercise and Korean dance movement exercise. Physical fitness consisted of grip strength, upper and lower body endurance, cardiovascular endurance, flexibility, balance, coordination. The posture was measured the static posture when standing, using a high-resolution camera, body style to automatically measure the distance and angle(M-zen, Korea). Posture was measured in both the coronal and sagittal plane via reference board. Fall prevention self-efficacy was measured via questionnaire using the Korea Falls Self-Efficacy Scale (FES-K). The physical fitness, posture and fall prevention self-efficacy were measured twice with pre and post exercise, and the difference between groups with Wilcox signed rank test, and the group-specific post verification was carried out with U-validated methods (Mann Whitney U test). Statistical significance level was verified by setting the p<.05. Lower body endurance, cardiovascular endurance, flexibility, balance and coordination significantly increased in the experimental group. The control group was no significant increase in physical fitness variables. shoulder slope angle, pelvic slope angle(coronal/sagittal), leg length difference, scapular inferior angle and left/right calcaneus angle significantly decreased in the experimental group. Both the experimental group and control group were no significant increase in fall prevention self efficacy. The prevention of falling exercise program for elderly women indicated the positive changes in physical fitness(except grip strength) and posture(except upper body slope). However, there are no significant differences of falling prevention self-efficacy between the both group. Thus, the prevention of falling exercise program for the elderly has been proved that it is highly efficient on improving physical fitness and posture proofreading. However, we still need to consider supplement exercise for grip strength and upper body slope.
